Looking for any documentation on these: https://archive.org/details/buffalo-paperwork/ I was able to scan what I had from a Computer Reset NIB unit (Buffalo XL), but there was no DIP switch reference. I did take a picture of the DIP switches as they exist and put the JPG in the Archive page...

Hey, everyone! Has anyone attempted to make a DuPAL to reverse engineer PALs? I've got one built - and am pulling my hair out trying to get it programmed. I've tried reaching out on the Arduino forums (and not getting much help there yet - they wanted schematics and everything first), but...

I have some TI CC-40 systems that seem to have bad Zebra stripes. Or at least, that’s what I figure. I can get parts of the LCD pixels that are missing by gently pressing down on the bezel. I’ve tried cleaning the stripes and LCD with alcohol - no dice. I think the stripes just might be...

Hey there. I have a M396F 386 SX 33 board in a case and am having trouble getting the turbo LED and display to work correctly. None of the diagrams on Minus Zero degrees match mine. Here’s the first problem: As hooked up, the LED display shows a 16 when turbo is pressed and the Turbo light...

I picked up a couple of these from Computer Reset, and they're cute! I notice they not only have infrared, but also a RJ11 jack on the back. Do they natively use the XT protocol on the wired connector, or is it proprietary to the PCJr? Has anyone created an adapter that will make these work...

All of these were the same unit. I’m looking for either a working unit or one that I can use for parts. I am also looking for the serial card for this printer too. Thanks!!!

I have some Signetics PALs that I need read, and my programmer doesn't support them. I also have an AMPAL16R4APC. Does anyone know how I can get read some PLS153N (if the fuses support it)? My 844USB and my TL866 don't support them. If the fuses are blown, are there any reverse...

Trying to figure out if there’s a way to dump this via software so I can get it to the MESS folks. This is the 1100 character rom. I’d rather only desolder it as a last ditch effort (I’d have to pry the label off and figure out what kind of chip it is, too.) Any thoughts? Thanks!

I have a Sensation 1 and am looking for some parts if anyone has a parts unit.... 1) Power Supply - if not, no worries, I'll just have to build one with a PicoPSU and a breakout ATX board 2) Modem and the modem cable I an open to trades and such if anything is needed. I have a literal boatload...

I saw this on eBay this morning. (Not mine) This is like the Tandy 1100FD - except two differences: 1) It has a backlight! 2) The ROM does not have DeskMate. However, everything else is exactly the same as the 1100FD. This model has the rare unicorn of a 1MB EMS card in it that can be used...

I've found while working on older 486 and early Pentium laptops that a lot of them use 26 pin FFC cables - but 1.25mm ones. This includes laptops as old as the Tandy 1100FD all the way to my Toshiba 405CS. Almost all the replacement servo-based floppy nowadays are still 26 pin FFC - but they're...

I have some stuff they might want to put up in a shared folder, but there's no contact button. Anyone here know who runs it?

In case anyone with Google ever finds this thread. I know people purchased this service manual - we still don't have a scan of it anywhere. If you have one, please consider letting me know! I'd be glad to compensate for time for scanning or outright purchasing the item so that I can scan it!

I have this 8 bit GW 451 I/O card that I’m looking for information on. It has a DE25 female (parallel?) and a DE15 (joystick?) connector on the back. It has two ASYNC ports on the board (serial). Seven jumpers and three missing ICs. https://www.icloud.com/sharedalbum/#B0YG4TcsmGXK00e...

There was an old shareware DOS menu-ing program in the 90s called "GECMenu" (I believe) - Gary E Carpenter was the author. Google cannot find heads or tales of this program, but I remember it being on a BBS back in the day. It was a really cool program that let you set menu descriptions...

I was thinking about getting one of these - but this was from my days when I was using my Commodore Amiga (after my Tandy 1000 days).... I know EMS is more limited with program types, you can't do DOS HIGH like with XMS (and DOS 6), but what else can you do with one of these things on my...

I have a large cache of 5 1/4" and 3.5" drives that I need to test. I do have a variety of older PCs that I can use, and also a Kyroflux. The Kyroflux looks like low hanging fruit to test, but has anyone used it in the manner to test floppy drives? I want to make sure they're reading and...

TL;DR; Does anyone know offhand what floppy models are direct drive and 26 pin 1.25mm FPC? I can order a couple of whatever to try out. As far as slimline floppy drives (i.e. laptops and servers) go, I have need of a 1.25mm FPC variety to replace a dead floppy. (It's actually REALLY hard to...

Got two emachines from the FIL while in his old warehouse. I found media for the 733i one on eBay :). Not having luck for the 333CS one. Anyone have media by chance (or an iso)? I did find the 56K modem driver cd for the 333, we just couldn’t find the main recovery media. Thanks!

I don't see this anywhere else on the interwebs, so hopefully this helps. I have an EP-1 programmer that I got from a friend, and the device lists aren't anywhere on the net. Here you go :) Also, the manual is here: ftp://ftp.mrynet.com/Hardware/PROM/EP1.PDF >PARTS AMD 8753H *1B,C...
